Method and system for acquiring information by mobile terminal and applying the same

The invention discloses a method which acquires and applies information through a mobile terminal and a system thereof. The method includes the steps that: information data is acquired through an information acquisition module of a mobile terminal; a feature processing module extracts the eigenvalue of the information data; an application processing module can directly conduct an application according to the extracted eigenvalue and also can send the extracted eigenvalue to a retrieval module of a data processing server; the retrieval module conducts data retrieval in a memory module according to the eigenvalue received and acquires the data retrieval result; the data retrieval result returns to the application processing module on the mobile terminal; the application processing module conducts corresponding application processing according to the data retrieval result. By applying the method and the system provided by the invention, different applications can be executed by conveniently utilizing the information acquisition function of the mobile terminal and the functions of the mobile terminal can be effectively expanded.
